Specication of Letters Patent.

Application filed February 27, 1912. Serial No. 580,171.

To all whom t may concern:

Be it known that I, PETER L. GARDNER, a citizen of the United States,residing at St. Cloud, in the county ot Stearns, State of Minnesota,have invented certain new and useful Innnovements in lVrenehes; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable othersY skilled in the art towhich it appertains to make and use the same.

This invention relates to improvements in wrenches, and has 'for itsobject to produce a device of this character which is simple inconstruction, efficient in operation, and one which may be manufacturedat a small cost.

A further object of the invention is to produce a wrench which may beeasil'y and quickly adiusted to remove or tighten nuts or pipes ofdifferent sizes.

With these and other objects in view the invention consists in certainnovel features of construction, combination and arrangement of parts aswill be hereinafter fully described and claimed.

In the drawing: Figure 1 is a side elevation of the device. Fig. 2 is atop plan view. Fig. 3 is a' sectional View on line 3 3 of Fig. 1.

Referring to the drawing, the numeral 1 designates the shank, the samebeing preferably rectangular in cross section, and at one end o1 whichis formed a fixed jaw 2, the inner face of which being preferablyprovided with serrations 3. Formed integral with 4the shank 1, and uponopposite sides thereof are laterally extending flanges 4, said flangesbeing adapted to slidably receive the curved lips 5 formed upon the rearedge of the movable jaw 6. The movable jaw (i is also provided withserrations 7 which in conjunction with the serrations 3 of the jaw 2serve to cla-mp a nut or pipe in an effective manner. A slot 8 is formedintermediate the ends of the shank l, and passing therethrough is atransversely arranged pin 9 by which the reversely curved end 10 of thelever l1 is pivotally connected.

To move the jaw 6 toward or away from the jaw 3, a link 12 is provided,both ends of which being formed with furcations 13, and by which thelink is pivotally connected to the jaw 6 and extreme front end of thecurved end 10 ot the lever.

Formed upon the upper edge of the shank L is a circular lug 14, asimilar lug being.

also Al'ormed upon the lower edge of the lever 11, the same beingdesignated by the numeral 15. Interposed between the lever '11 and shankll is a coil spring 16, the lugs 14 and 15 serving to prevent accidentaldisplacement of the shank. The coil spring 16 tends to force the lever11 outwardly and away from the shank '1 whereby the movable jaw 6 isnormally held out of engagement with the jaw 2.

IVhen it is desired to adjust the jaws for gripping a nut or the like,it is only necessary that the operator grasps the shank 1 and lever 11,so that the hand spans the same, whereupon pressure being applied, thejaw 6 is moved forwardly and the article is gripped.

What is claimed is:

The conibination with a shank having a fixed jaw formed at one end,laterally extending flanges carried by the shank, a second 'jaw havingits upper edge provided with curved lips for slidably engaging saidflanges, a slot 4t'ormed intermediate the ends of' the shank, a 'leverpivotally connected intermediate its ends in the slot, a link havingAfui-cations formed upon its opposite ends between which is pivotallyconnected one end 'of the lever and the second jaw, and means interposedbetween the` shank and lever for holding the second jaw normally out ofengagement with the first named jaw.

In testimony whereof, I affix my signature, in presence of twowitnesses.

PETER L. GARDNER.
